PITTSBURGH (KDKA) – An elderly woman was killed and her daughters hospitalized after an intense fire consumed a home overnight in Richland Township.

A huge cloud of thick smoke poured from the home in the 1000-block of Woodhill Drive.

Neighbors say the fire started around 3 a.m. with flames quickly engulfing the residence.

“There were a couple of explosions,” said Robert Maker, a neighbor. “Apparently, there were some oxygen tanks inside, and that woke us up. Then, we came out and the house was pretty much fully engulfed.”

“We just heard a big bang,” added Hanna Clogan, another neighbor. “We thought it was gunshots, and I look out my window and I just see the house on fire.”

An elderly woman and her two daughters were inside when the fire started.
